Description

Orientation tool and detection tool

Technical Field

The utility model relates to the field of mechanical measurement, in particular to a directional tool and a detection tool.

Background

The sleeve type part is a hollow rotary part, is generally used as a bearing structural part or a guide structural part, can adopt different structures and sizes according to different functions, and has different requirements on the structure of the part.

The snap sleeve belongs to one of sleeve parts, mainly plays a role in positioning connection and bearing radial force and circumferential force, and has higher requirements on relative positions and sizes of structures such as holes and grooves on a shaft.

The hole and groove structures are uniformly distributed on the surface of the cylinder, and the sizes of the relative positions of the hole, the groove and the shaft cannot be measured by conventional inspection means such as a caliper and a height gauge. If a three-dimensional measuring instrument is adopted for measurement, the efficiency is low, the procedure is complex, and the method is not suitable for inspection in the production process of mass parts. When a projector is used for measurement, the hole and groove structures of the part cannot be effectively adjusted under the projector only by visual inspection, and the measurement result has larger deviation.

Therefore, it is necessary to develop an orientation tool for orienting the snap sleeve to be detected and aligning the hole and groove structure thereon.

In order to make the technical purpose, technical solutions and technical effects of the present invention more clear and facilitate those skilled in the art to understand and implement the present invention, the present invention will be further described in detail with reference to the accompanying drawings and specific embodiments.

1-3, FIG. 1 shows a schematic structural view of an orienting tool in accordance with a preferred embodiment of the present invention; FIG. 2 is a schematic diagram of the centering constraint of the orienting tool of FIG. 1; fig. 3 shows a schematic view of the centering restriction structure shown in fig. 2 in another direction. Specifically, the orientation tool comprises a V-groove body 100 for the placement of the snap sleeve 200 and a centering limiting structure 300;

centering limiting structure 300 includes a sliding block 310 slidably disposed in V-shaped channel 100 and a protruding orientation limiting member 320 formed protruding from sliding block 310 for cooperating with a hole or slot on snap sleeve 200 to orient snap sleeve 200.

The technical scheme is a basic scheme, and the fastening sleeve 200 is limited in the V-shaped groove body 100 by utilizing the principle of three-point circle and adopting the protruding directional limiting piece 320 and the V-shaped groove body 100; the orientation of snap sleeve 200 is accomplished by the mating of male orientation limiter 320 with a hole or slot in snap sleeve 200. And then the position size of the hole or the groove on the buckle sleeve 200 can be obtained through measurement by a projector.

The sliding block 310 comprises a V-shaped portion 311 slidably disposed in the V-shaped groove body 100 and a connecting portion 312 integrally formed with the V-shaped portion 311;

a convex orientation restriction 320 is convexly formed at the connection portion 312.

Here, the V-shaped portion 311 is sized and shaped to fit the V-shaped channel 100. Thus, the sliding block 310 can smoothly slide in the V-groove 100.

Further, the convex orientation restriction member 320 includes a root portion 321 convexly formed at the connection portion 312 and a wedge portion 322 integrally formed with the root portion 321. Here, by using wedge 322, a range of sizes of holes or slots on snap sleeve 200 may be fitted.

Furthermore, the utility model also provides a detection tool which comprises the orientation tool.

The utility model provides a directional tool for measuring the relative position sizes of holes and groove structures on shaft parts such as a buckle sleeve to be measured, which is used for assisting detection equipment, the V-shaped part 311 of a sliding block 310 is used for limiting two moving degrees of freedom and two rotating degrees of freedom on the parts such as the buckle sleeve, the side surface of a wedge-shaped part 322 protruding out of a directional limiting part 320 is matched with the edges of the inner walls of the holes and the groove structures on the buckle sleeve to limit the other moving degree of freedom and the other rotating degree of freedom, and the centering and the alignment of the part structures are completed.
